Fix & improvement getPedMoveState

[FileEX]

Fixed #1598 #1594 #1590

The getPedMoveState function behaves somewhat unreliably. It often incorrectly returns fall, which is caused by the imprecise behavior of IsOnGround (in some areas of the map, the player's position might be, for example, z = 8.5, while the ground is z = 7.5).

This PR fixes the mentioned issues and adds new states (previously incorrectly labeled as fall):

• swim
• walk_to_point (when a ped is walking to a vehicle door to get in)
• ascent_jetpack – ascending with jetpack (space key)
• descent_jetpack – descending with jetpack (shift key)
• jetpack_flying – flying with jetpack
• roll - Added the previously planned roll state

Here is a screenshot of one of the reported issues I received:
